IMPROVEMENT IN CLOD-CRUSHERS.

Specification forming part of Letters Patent No. 155,975, dated October13, i874; application filed August 28, 1874.

To all whom it may concern:

Be it known that I, RUSSELL B. REDFIELD, of Harrisville, in the countyof Medina and State of Ohio, have invented a certain new and Improved(Hod-Crusher, &c., of which the following is a full, clear, and completedescription, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 is a plan view of theclod-crusher. Fig. 2 is a front view. Fig. 3 is a side view. Fig. 4 isan under-side view.

Like letters of referencerefer to like-parts in the several views.

This invention has for its object the crushing and pulverizing of clodsin the cultivation of the soil, whereby the ground is worked into propercondition for planting and the sowing of seed.

Said invention consists of a series of revolvin g cutters together withan arrangement of stationary cutters or blades cooperating therewith.

The construction of the implement is as follows: A, B, and G, are piecesof timber, longitudinally arranged parallel to each other, as shown inFig. l, and transversely in an oblique direction, as shown in Fig. 3.Said pieces of timber are secured together and in the relation shown, bythe side pieces or ties D D. To the lower corner of each of the piecesof timber is fitted a rectangular plate or angle-iron, E, Fig. 3, fromwhich projects a series of rectangular blades, F, Fig. 1, having sharpcutting-edges, as seen at a. In front of the timber A and paralleltherewith is secured a timber, G, also having an oblique direction. Thelower corner of said timber Gr is cut away to a groove, in which issecured a shaft, H, Fig. 4, Whereon are hung and re volve the wheels orcircular cutters I, so arranged in relation to the first series ofcutters F as to be relatively between them, as will be seen in Fig. 4.

This particular arrangement may be varied,

lands that are clayey, hard and large lumps or clods of grass willremain unbroken, notwithstanding the most thorough harrowing,

and which cannot be reduced by the harrow. A roller is sometimesemployed to crush them; but this is objectionable, as it rolls down andcompacts the tilth, which should be light and free, and unless it isgone over again by the harrow the ground is in bad condition forseeding.

To avoid the use of the roller and harrow is the purpose of theimprovement above de scribed, and which is used directly upon thenew-plowed field Without a previous or after use of a harrow.

As the implement is drawn forward the revolving cutters I sever theclods and lumps over which they pass, which are further out and brokenup by the stationary cutters F. The clods and lumps thus cut and brokenup by the cutters are torn and crushed by the lower edges of the timbersA B O on passing over them, the machine being suificicntly heavy tobreak them into tilth Without forcing them down into the ground andpacking it, as would be the result of rolling with a field-roller, andin the event the edges of the timbers should press hard upon the groundand slightly packing it, the cutters following will stir up thecompressedsurface and leave it free, open, and light for seeding.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the revolving cutters I, stationary cutters F, andtimbers A B 0, arranged obliquely in relation to each other, in themanner substantially as described, and for the purpose specified.
